Accidental Entrapment of Electrical Mapping Catheter by Chiari’s Network in Right Atrium during Catheter Ablation Procedure

Figure 2

The images of fluoroscopy. Right atriography revealed the entrapped catheter was distant from tricuspid valve, posterior wall of right atrium (RA) in left anterior oblique (LAO) view (a), and lateral wall of RA in right anterior oblique (RAO) view (b). The head of multiloop mapping catheter was apart from tricuspid annulus (TA). The forceps (arrow) designed for endomyocardial biopsy caught the head of multiloop mapping catheter and twined connective tissues (c).
